Proteja o Chefe (2011)

No Eun Seol finally gets a job as a secretary at a law firm after struggling with unemployment, only to have her boss, Cha Ji Heon, the immature youngest son of a chaebol family, fall in love with her.

both lead male character keep acting like kids
in both drama the girl is poor while the man is rich

A strong girl and a stubborn rich brat that won't accept "no" for an answer..and we also have a "soulmate"? The perfect combination.

Both dramas are romantic comedies about a female bodyguard who has to protect their famous snobby boss and end up falling in love with him.

Both have a funny rich guy lead and a feisty female who eventually fall for each other.

In Protect the Boss, No Eun Seol becomes Cha Ji Heon's secretary. She whips this immature, rich man into shape and falls in love with him. In How to Meet a Perfect Neighbor, Jung Yoon Hee becomes Yoo Joon Suk's secretary. She cracks his cold, businessman shell and falls in love with him.

Both dramas are very similar.

ML are practically the same.
FL is an assistant that falls in love with the boss.
ML realises first his feelings first in both dramas.
Naturally, it has an SFL that don't deserve ML but uses status.

boss & secretary relationship that begins with lots of fight and bickering and end up being lovey-dovey couple

Both dramas are set within companies but somehow they manage to be hilarious.
Keep in mind that Salaryman is a melodrama though so it's not as lighthearted as Protect The Boss but you should still give it a try. You won't regret it!

No Eun Seol finally gets a job as a secretary at a law firm after struggling with unemployment, only to have her boss, Cha Ji Heon, the immature youngest son of a chaebol family, fall in love with her.

It has a boss who needs protection from society, cameras and attention. Rom coms and have similar vibes.

-Overall very similar vibe
-Both are actually funny, like I-almost-peed-laugh-out-loud-cute-funny
-Guy is chick's boss
-Chick is a badass but gives off a natural vibe of something else (Strong Woman: chick is supa cutesy, Protect the Boss: chick is awkward and cringey but amazing)
-Workplace romance that started from experience with chick kickin' the crap outta some dudes that actually had nothing to do with the workplace and then it does cuz then she's hired and batta-bing batta-boom
-Love triangle-y
-Leading dude is kinda wimpy, but then wants to protect the chick, but then again he's kinda wimpy (he will have his strong moments tho)
-SUCHHH ROM AND SUCH COM (Protect the Boss gets a lot more serious toward the end, whereas even Strong Woman's most dramatic moments had a comedy vibe)
-Lots of powerful quotes
-DANNNNG that chick can speak for herself
-AANND she can hold her own. Yeah that's right male lead, I'm looking at you, that means she's just as fine without you or any man for that matter
-A good female friendship between main character and side character (Protect the Boss has multiple female friendships)
-A funny, awkward butler-y secretary of dude guy
-Guy falls (in love) first

They both involve a female body guard with a male boss that they find it hard to get along with at first.

TROT LOVERS and PROTECT THE BOSS are both Romantic Comedies. Both have the couple start out disliking each other. Then they get close after working together. Both have men that mature throughout the drama. I would described both as fast paced and fun, because they both are upbeat and there is always someone running here or fighting there..
